“In that moment, Ioan realised that he had to allow his dad to have this space.”

Laverne leaves the family for a couple of weeks to see how they get on.

On her return, Laverne asks Adrian and Emma if they’ve noticed any differences.

Emma is far less bruised and the couple have managed to get him into bed in around an hour each night – and seem more together as a result.

The expert then goes on to try and strengthen the bond between father and son – something that has been lacking.

By the end of her visits, Laverne is impressed with the family’s progress.

She tells the parents: “What we have now is something that seems much more balanced and I think that balance is very strongly linked to the fact that you two are much more united and able to show him a very different way of which you can be parents together.”

Emma acknowledges: “We’ve kept him too young; we’ve not been the parents he needed us to be.

“I can’t believe how strong he has been to change this quickly.”

Laverne adds: “When I arrived, this was a family who felt at breaking point, Ioan’s behaviour, his violence and aggression really dominated family life.

“Now, they’re building better and stronger relationships.

“If they can keep building those relationships then they really do have a good chance of becoming a family who are much happier.”
